Hi! I just bought one of those fire sale 7300's and I have a few questions I hope someone can answer. 1) Does anyone have a list of all the commands available under the "expert" mode of the diagnostics? i.e. type s4test at the user menu prompt. I puttsed a little but since I didn't know what I was doing I thought it best to back off. 2) Does anyone know how to create multiple partitions for a drive? The /dev directory seems to imply that one can have up to 16 partitions, do you have to invoke some magic from the above stated expert mode of diags? My idea is this: 6 partitions: 0: 32 blocks for boot/loader 1: 5000 blocks for swap/paging 2: 3200 blocks for /tmp 3: 13000 blocks for / 4: 13000 blocks for /u 5: 4984 blocks for /usr/spool ----- for a total of 39216 aka a 40M drive The main reason I want to break things up is to reduce the time to do backups. / and /u are the only ones that need backing up and / is basically a read only partition so it only has to be backed up once. 3) For you fire sale "My battery is DEAD" people. When I first powered up the 7300 my battery was dead too, it wouldn't hold the time. Now, a week later, when my used 20M self destructed and I had to put the 10M back in, B^(, the battery held the time for 3 hours. ( Lunch time interfered there, it only took 45 minutes to rip out the 20M) Maybe the battery can partially recharge when the machine is turned back on. Any info would be greatly appreciated, -Rob Healey rhealey@ub.d.umn.edu

Observing the same phenomena, I put a current meter in series with the battery. When the machine is turned on, the battery does indeed "charge" with a small current. I seem to recall that technically the lithium batteries used are not rechargable-- however, they do seem to tolerate a small amount of reverse current. Don Parmentier donp@cup.portal.com
